How to derive an interval from two dates?

Open on Drupal.org →

Created on 11 January 2024, 6 months ago

I'm developing a classified ads system which includes a custom entity type. It has an expiry date field and a 'time_remaining' interval field that is to be calculated and stored when users pause their ads.

How would I programmatically set the interval field value based on the time between now() and my date field?
And if I store the period in hours, is there a way of displaying the time remaining in days? Or should I be using the duration_field module instead? I'm trying to stick to dependencies of commerce and related modules where possible.

👋 I wrote this module for a classifieds site many years ago so glad to see it go full circle.

There are two properties on the field https://git.drupalcode.org/project/interval/-/blob/8.x-1.x/src/Plugin/Fi...

the interval and the period, the period corresponds to one of the interval plugins - https://git.drupalcode.org/project/interval/-/blob/8.x-1.x/interval.inte... e.g 'second' 'minute'

and the interval is the quantity

There's some examples in the tests - this one sets the value to 30 minutes - https://git.drupalcode.org/project/interval/-/blob/8.x-1.x/tests/src/Ker...
